Apparatus for manufacturing high pressure inert gas
Abstract
Abstract THIS INVENTION RELATES TO AN APPARATUS FOR MANUFACTURING HIGH PRESSURE INERT GAS UTILIZING HYDROCARBON FUEL, THE GAS BEING PRODUCTED BY THE BURNING OF HYDROCARBON FUEL IN AN INTERNAL COMBUSTION ENGINE, THE EXHAUST GASES THEREFROM BEING CONVEYED THROUGH A CATALYTIC CONVERTER WHEREBY SUBSTANTIALLY INERT GAS A DERIVED THEREFROM, AND INCLUDING MEANS OF CONTROLLABLY RECYCLING SUCH INERT GAS THROUGH ENGINE DRIVEN COMPRESSOR STAGES TO VARY THE LOADING ON THE ENGINE AND THEREBY VARY THE INERT GAS OUTPUT IN RESPONSE TO THE DEMAND. AN ADDITIONAL EMBODIMENT OF THE INVENTION INCLUDES MEANS TO MAINTAIN A POSTIVE PRESSURE IN ALL PORTIONS OF THE SYSTEM, INCLUDING THE ENGINE ENHAUST MANIFOLD AND CATALYTIC CONVERTER, SO THAT ANY INADVERTENT LEAK IN THE SYSTEM WILL NOT RESULT IN AIR BEING DRAWN INTO THE SYSTEM.
